Physics- Work done by a force

• Work done


  Whenever energy is transferred from one store to another
• Types of work


  • Mechanical work
  • Electrical work
• Mechanical work


  • Using a force to move an object
• Calculating work done


  Work done (J) = Force (N) x Distance (m)
• Calculating work done in car braking example

  1. Work done (J) = Force (N) x Distance (m)

  2. Work done = 2,000 N x 20 m

  3. Work done = 40,000 J
